What Rule #1 is
When someone using Fusion 360 mentions Rule #1, they refer to an unwritten rule within the Fusion community that, when first starting a design, you need to be sure to use components. If you don’t plan on using components, your timeline and browser will get very large, making it difficult to locate objects. This helps not only you but also anyone else who you may want to collaborate with on a project.
What components are
A component is basically like a top-level assembly of a part. You can also think of it as a large box that stores all the basic pieces that make up your 3D part, which could be the sketches, the construction planes, the solid body, and so on. This helps with the organization of parts and will shorten your timeline at the bottom of the Fusion 360 user interface if you have a large assembly model.
